'House' of cards? No, he stacks skyscrapers

Bryan Berg spends much of his life in a house of cards. Literally. Berg, the Guinness World Record-honored "Cardstacker," has devoted his career to building houses of playing cards -- and skyscrapers, domes, cathedrals and stadiums, too.

As with any house of cards, these unbelievable creations can come crashing down at any moment. However, almost in defiance of gravity, they remain standing until Berg decides it's time to blow them all down.

Berg, 33, is one of those lucky people who makes a living from his hobby. He travels across the United States putting on shows in which he builds seemingly impossible structures out of ordinary playing cards.
